floppy.sys problem

[Hartmut Birr]

Hi,   

with my last changes it is possible to install ros from the boot cd and
select the floppy as boot device. Currently there exist three problems.
After selecting the floppy as boot medium it is shown a dialog box which
does mean, there is no disk inserted. A second try detect the disk. The
installer copies all files to the floppy disk. After trying to restart
the computer, ros hangs. I must manually reset the pc. The floppy disk
is still inserted at this point. The pc does boot up, accessing the
floppy disk, shows 'Loading FreeLoader...' and shows 'Disk error \nPress
any key". Pressing a key results in the same message. If I remove and
insert the disk again, I can load freeloader from the floppy disk and it
does boot reactos. It seems, that the bios isn't able to initialize the
floppy controller correctly after reactos was running. I've added a
shutdown procedure in floppy.sys which resets the floppy controller over
the DSR register, but this doesn't help. Has anyone an idea what is
wrong?
